Effect of Target Temperature Management on Intestinal Flora and Its Metabolites in Patients With Cardiac Arrest

Sponsor: Capital Medical University

Summary

Based on the self-control design, this study explored the dynamic regulation of target temperature management therapy (TTM) on intestinal flora structure and metabolites of patients after cardiopulmonary resuscitation (CPR). This study is a single-center prospective observational study. Patients with spontaneous circulation recovery (ROSC) after CPR and TTM were included before and after self-hypothermia treatment, and the time series changes of intestinal flora and metabolites at some representative time points before and after treatment were compared. Thirty-five adult patients (age ≥18 years) who met the admission criteria were included. Before TTM treatment (0h after ROSC, baseline), 48 h after TTM warming (T1) and 48 h after rewarming (T2), fecal samples (macro-gene sequencing) and blood samples (metabonomics) were collected to analyze the changes of intestinal flora and metabolites in patients with cardiac arrest, and to screen the differential flora and metabolites regulated by TTM and their dynamic correlation.
